PRONAL compensators

Generally fitted on the interior of hydraulic tanks and operating with no energy source, hydraulic compensators offset variations in the volume of oil or any other fluid associated with changes in temperature or volume, thereby ensuring the protection of hydraulic circuits. On the interior of hydraulic tanks, oil is not in contact with air.

PRONAL compensators or bladders also ensure the complete leak-tightness of tanks, and protect hydraulic fluids against any external contamination by the provision of a totally deformable membrane as a barrier to the external environment. They can also assume the function of a hydraulic damper.
